WCCO reports that Quasi’s condition “formed when his soft vertebrae compressed, causing his spine to shrink.”

He has to undergo several surgeries; the first of which was performed Monday. Officials with Secondhand Hounds say Quasi is also suffering from frostbite, ear infections and also had injuries from an embedded collar.
